It sure sounds your bin thermistor, 2313633, is bad. Make sure your meter can read high resistance, the thermistor should have 10k ohms at 77°F. Did you put the machine into diagnostics? I have attached the tech sheet.

The bin thermistor should have a resistance value of 83K - 99K ohms @ ice bath temperature. It is the switch for monitoring the full bin status that shuts harvesting down & turns it back on. Sounds like your bin thermistor is defective. Replace it so it senses a full bin of ice.
